7 Claims. (01. 281-33) This invention relates to portfolios of the type trated at 5, and 1 respectively. The hinge 6 at used by salesmen and generally for advertising the apex is preferably in the form of a loop wire and display purposes and has for its object to prodevice which serves not only as a hinge for the vide an improved device of this type which will two walls 2 and 3 but also as the support for the 5 have a greater scope of utility. pamphlet l which may therefore be of the loose 5 Another object is to provide a tripod type of leaf type. support having one wall hinged along its median The base wall 4 is hinged at 8 along its median line and hence collapsible between the other two line so that upon elevation of its hinge the walls walls in order that the support and its leaflets 2 and 3 will collapse against each other as illus- 10 may be collapsed into a flat form for easy hantrated in Fig. 2. Whenthe support is opened in dling. into the position best shown in Fig. 3 it is ready for .A further object is to provide a collapsible sup-- use. The leaves may be swung upwardly from port as above described which will also include a their lower edge and allowed to rotate about the stiff frame, as of comparatively heavy wire, which hinge 5 to the wall 3.

By this arrangement the The retainer has two wings joined by a trough reverse sides of one leaf may carry data, pictures portion hi, as best seen in Fig. 7, the wings being or information of particular relevance to that on pierced at [5 for bolts or beads. The retainer is 20 the front of the page next in order and when the fixed to the wall 2, the trough M and the adjacent first leaf is folded upwardly against the rack both wall'forming a guide for the legs 3.

The 40 Fig. 3 is. a view similar to Fig. 2 with the side frame is thus inconspicuous when in retracted 40 walls spread apart as permitted by the base, position and does not interfere in anyway with Fig. 4 is a view similar to Fig. 1 with the rack the collapsing of the walls 2 and 3 against each extended, other as shown in Fig. 2.

Fig. 5 is a view similar to Fig. 3 with the rack What I claim is:- extended, and 1. A portfolio comprising a leaflet, a triangular 45 Fig. 6 is a perspective detail of one corner of support for said leaflet, the leaves of said leaflet the triangular support, being hingedly mounted near one vertex of said Fig. 7 is a perspective detail of the frame resupport and resting against one wall thereof, and tainers with the leg of the frame therein. a frame having the legs thereof slidably mounted More particularly, l indicates the leaves of a on one wall of said support for extension and 50 booklet which lie against a relatively stiff wall 2 retraction of the outer edge thereof with respect of a triangular support composed of the side wall to the hinge of said leaves, said leaves being 2, another side wall 3 and a base wall 4. Each of swingable through a vertical arc about said vertex the walls 2, 3 and 4 is hingedly connected at each to a position of rest against said frame when in Q5 edge thereof to the two adjacent walls as illusextended position.

2. A portfolio comprising a leaflet, a triangular support for said leaflet, the leaves of said leaflet being hingedly mounted from the apex of said support and resting against one wall thereof, and a frame having the legs thereof slidably mounted on one wall of said support for extension and retraction of the outer edge thereof with respect to the hinge of said leaves whereby said leaves when turned find a position of rest against said frame when the legs are in extended position.

3. In a portfolio, a leaflet, a triangular support for said leaflet with the sides thereof hinged to adjacent sides, the base side of said support being hinged along a median line whereby upon elevation of said median line the other two sides collapse against each other, and a frame carried by said support having the legs thereof extensible from a retractible position between said other two sides, said frame when extended constituting a rest for the leaves of said leaflet when they are turned.

4. In a portfolio, a leaflet, a triangular support for said leaflet with the sides thereof hinged to adjacent sides, the base side thereof being hinged along a median line whereby upon elevation of said median line the other two sides collapse against each other, the hinge at the apex of said support being of a loop wire type and constituting also the means for hingedly supporting said leaflet, the leaves of said leaflet being adapted to turn about said apex and come to rest against the opposite side of the support, and a frame of bent wire having the legs thereof slidably mounted on one of the upright sides of the support on the inner side thereof with the crossbar thereof parallel with said apex, said frame when extended constituting a rest for said leaves when turned upwardly thereagainst.

5. A portfolio comprising a leaflet, a triangular support for said leaflet with the vertical sides thereof collapsible against each other, a loop wire hinge connecting the adjacent edge of said vertical sides and constituting also the support for said leaflet, said loop wire having an overall length substantially less than the length of the apex of said support, one of said vertical sides being notched on each side of said loop wire hinge, a bent wire frame having a cross bar outwardly of said support parallel to said apex with its legs projecting through said notches and between said vertical sides, and a retainer for said legs secured to the other side of said vertical sides immediately below said notches, said legs slidably engaging said retainers whereby said frame may be extended outwardly to constitute a position of rest for said leaves when they are turned upwardly.

6. A support for a leaflet comprising a stiff wall against one side of which the leaflet is intended to rest, and a frame having spaced legs connected by a rail piece, said legs being slidably mounted on the other side of said wall for extension and retraction of said rail piece away from and against an edge of said wall, said frame constituting a rest for the pages of the leaflet when turned from their position of rest against said wall.

'7. A support for a leaflet comprising a stiff wall against one side of which the leaflet is intended to rest, means supporting said wall in substantially upright position, and a frame comprising leg means and a bar associated with said wall, said leg means being slidably mounted on the other side of said wall for retraction and extension of said bar toward and away from one edge of said wall, said bar and leg means serving as a support for leaves of said leaflet as they are turned from their position of rest against said wall.
